How to Set Custom php.ini file on my Web Hosting Service?

Please note that changes you made at php.ini file located at above path will be reflected globally. It will affect all php websites hosted on your server.

When you are required to make changes in some specific website, you can simply copy default php.ini file and copy it to wwwroot folder of the website. Similarly, if any subfolder of your website requires custom php settings, you can copy this file to subfolder and make desired php settings.

To verify that php.ini file is being loaded from website’s wwwroot folder (path where you have uploaded php.ini file with custom changes), you will need to create a phpinfo page. A phpinfo page shows all of your php environment settings. A phpinfo page is simply a php page with the following code.

<?php phpinfo(); ?>

To create a phpinfo page, create a plain text file in wwwroot folder of your website, paste above lines and save the file. The file name can be named anything, phpinfo.php is just a symbolic common name for this file. If you created the file in your wwwroot folder, then you should browse phpinfo.php like, http://<yourdomainname>.com/phpinfo.php. phpinfo page should look like following.

You can verify that php.ini is loaded from the correct path by searching “Loaded Configuration File” via browser's search feature ( Ctrl + f ). Similarly, you can also search for custom settings you have done to php.ini file and verify that those settings have been reflected.
